T0 all 'whom 'it may concern:

Be it known that I, JOSEPH BARRAJA- FRAUENFELDER, a citizen of theUnited States, residing at Bridgeport, in the county Y of Fairfield andState of Connecticut, have `a disabled sunken submarine boat, and toprovide means for attaching a hoisting cable to the disabled craftwithout the services of divers, so that the disabled craft may be eitherraised to the surface or hauled over the water-bed intol shallow waterwhere the rescue of the crew and salvage operations may be moreconveniently and expeditiously carried out.

'The invention consists in providing a marker-buoy which is firmlylocked in a cylindrical receptacle built upon or secured to the boat,said marker-buoy having messenger-lines detachably connected theretowhich are coiled in recesses or pockets formed in the receptacle andheld in place bythe lmarker-buoy, the marker-buoy being seatedwater-tight upon the receptacle to prevent water from entering saidrecesses or pockets in the event of the deck of the boat being washed byheavy seas or when ther boat is submerged under normal conditions,whereby the messenger-line is ke t dry and prevented from being damagedy the water.

The invention further consists in certain peculiar features ofconstruction, combination, and arrangement of parts'as will behereinafter fully described and then claimed.

In the drawings illustrating the invention, in the several figures ofwhich like parts are similarly designated, Figure 1 is a diagrammaticview illustrating the application of the invention. Fig. 2 is a verticallongitudinal section of a portion of the hull of a submarine boat andthe superstructure arranged thereon, and illustrating the marker-buoy inposition on its receptacle. Fig. 3 is a vertical longitudinal sectlon ofthe receptacle showing the marker-buoy in elevation and detached fromthe receptacle. Fig. 4 is a side elevation of the anchor-bolt used inconnection with the invention for attaching a hoisting cable to theboat. Fig. 5 is an inverted plan view of the markerbuoy. Fig. 6 is ahorizontal section of the receptacle drawn on the line a-a of Fig. 3.4`ig. 7 is a vertical transverse section drawn on the line b-b of Fig.3, illustrating the anchor-bolt in locked position in the receptacle.

1 designates a submarine boat having a superstructure 2 built thereon inwhich, preferably adjacent to the ends of the boat are wells 3, thewalls of the wells being fiared outwardly at their upper ends as atl 4.Within each well is a cylindrical receptacle 5 for the marker-buoy 6 andas the receptacles and marker-buoys are exactly allke in constructiononly one will be described. Each receptacle is cylindrical incross-section and formed at its lower end with a flange 7 which isriveted or otherwise rigidly connected to the hull plating 8 of theboat, and intermediate its ends is provided with a horizontal partition9 from which extends a tubular sleeve 10, having its upper end flushwith the top of the wall of the receptacle providing an annular recess11 and a central socket 12, which is of larger diameter intermediateits'upper and lower ends tol provide a shoulder 12 designed to beengaged by spring actuated pawls carried by anfJanchor-bolt as will beereinafter more fully described.- Within the lower end of the socket 12is a short sleeve 13 providing an annular recess or pocket 14 in thelower end of the socket 12 and in which is wound one section 15 of amessenger-line carried by the marker-buoy 6, the opposite end, orsection 16 of the messenger-line being wound around the sleeve 10 in thelower end of the annular recess 11. Extending from the lower side of thetransverse partition 9 are ears 17 in which is journaled a sheave 18,around which the messenger-line operates. As shown in Figs. 2 and' 3 oneend of the messenger line extends through an opening 19 in the partition9 which leads into the re cess 11, while the other end passes up throughthe short sleeve 13, said sleeve being provided with a. slot 20, wherebythe- Patented June s, 1915. l

messenger-line may be coiled in the Ypocket v 14 without extending theline entirely Y through the sleeve as illustrated in Fig. 2.

21 designates a guard vband arranged partly around the sheave tolprevent the messenger-line from jumping the sheave as will be readilyunderstood.

The marker-buoy 6 is hollow and ma be a metal casting or constructed ofs eet metal as desired, and is formed with ahead 22 having a convex topand tapering side Walls which are inclined inwardly from their uppertoward their lower "ends, the .angle of the walls corresponding to theangle of the upper end 4 of the well 3, so

that it will snugly twithin the well when locked in position upon thereceptacle.

. annular recess 11, and a hollow central section 24 which is designedlto snugly fit the upper end of the socket 12, the said sleeve 23 andhollow section 24 being of such a length that when in position in thereceptacle the lower ends thereof will rest upon the coiledmessenger-line as shown in Fig..2, to hold the coils in position andprevent them from being tangled. The end of the section 15 of themessenger-line is connected to an eye-bolt held in a recess 25 formed inthe lower end'oi` the said hollow section 24, and the end of the section16 of said messenger-line is connected to an eyebolt held in a recess 26formed in the lower fend of the sleeve'23. The lower side of the head 22is formed with annular recesses or sockets to receive. packing rings 2'(of suitable -material which engage the upper ends of the outer wall ofthe receptacle 5 and the top of the sleeve 10, respectively.

In order to securely lock the mar er-buoy in position upon'thereceptacle and to press the packing* rings firmly into engagement withthe up er ends of the wall of the receptacle an the sleeve to providewatertight joints, I provide the following arrangement :-Pivoted in ears28`- extending outwardly from the flared end 4 of the well 3, below thedeck 2 of` the superstructure, are pawls 29 having theirfree endsoperating through slots 30 formed in the section have their inner endsthreaded. Upon the.

threaded ends of the bolts operate hand wheels 35, the hubs of whichbear against brackets 37 and the inner ends of the 'stufing boxes 34, sothat as the wheels are rotated Athe rods 33 and their connections willbe raised and lowered to thus operate the pawls 29.Y By thisconstruction it will be under'- vstood, that, when the wheels arerotated in mitting its removal when the boat is on the surface of thewater and also permitting it to be floated to the surface when the .boatis submerged. From the lower side of the head 22 of the The invention sofar as described follows vbuoys proposed for use in connection withsubmarine boats, and it will be understood, that should the buoy bereleased when the boat is submerged it will rise to and float upon thesurface, the lengths 15 and 16 of the messenger-line'beingautomaticalluncoiled as the buoy rises to the surface. owever, inconnection with the invention as described I employ means for attachinghoisting cables to the4 receptacle, to lift the boat to the surface orto drag it over the water-bed #into shallow Waters where salvageoperations may be conveniently carried on. -As stated, the socket 12 isformed with a shoulder 12 designed to be engaged by spring actuatedpawls carried at the lower end of an anchor-bolt carried by a Vbuoys arefirst released and allowed to float to the surface and when icked up bya surface craft the end of t e section 15 of theline is detached fromthe buoy and connected to the yanchor-bolt, preferably as shown in Fig.'7, th'e end ofthe length 16 of` the line is then detached andas thehoistingcable is lowered the end 16 of the line is drawn upwardly tothus guide and pull the anchor-bolt into the socket-12, it being un`derstood that when the lower end of the anchor-bolt enters the said'socket 12`the pawls 42 will be pushed inwardly into their Y recessesagainst the tension of their springs until the upper ends of said pawlspass the shoulder 12 of the sleeve 10 when the springs will force them,l outwardly and under the shoulder 12 thus locking the anchor-bolt tothe receptacle, after which, by suitable hoisting apparatus, the sunkencraft is either drawn to the surface of the Water or hauled over thewater-bed into shallow Waters as previously described.

It will thus be seen that the invention is exceedingly simple inconstruction and that a hoisting-line lor lines may be readily connectedto a disabled sunken submarine boat without the employment of divers,irrespective of the depth of the water in which the boat may have beensunk, and will be found particularly advantageous in recovering adisabled craft when it has been sunk be ond the working depth of divers.It wil, of course, be understood, that while not shown, suitabletelephone Wires may be carried by the marker-buoy whereby communicationbetween a surface boat and the sunken boat may be established. As thisfeature forms no part of the present invention I have not thought itnecessary to describe it in detail nor to illustrate it.
